Joule Thief

Jeanna:

Remember my video a while back where I accidentally discovered that, if I touched the transistor, my led lit up again? This was my video of one of my first JT supercaps circuits.  There may be something to this we don't understand. (won't be the first time, ha ha) 

This is why I love our think tank here.  Who knows who will come up with something that "should" not be?

I'm not sure you have the same setup as mine, was your coil a part of a joule thief ? I suppose when i shake mine it just boost the energy coming from my earth cell who give continuously a little amount of power(~0.6V and less that 1mA).

No. It was just a coil hooked to a peak voltage detector. I was curious to see how much voltage could be generated just by shaking a coil in the air. It was a lot more than I expected. But I was using a bigger coil than yours.

You have to realize that our bodies can induce voltage potential.
I have a 11' tower with 2 aluminum plates on top of it.
See picture.

If I hold each meter lead to each wire with my thumb and first finger I get a lot more voltage potential then if I just touch the meter leads to each wire.

Our bodies have a voltage potential.  Especially when we are standing on the ground outside.

So if you are holding the coils and shaking them then maybe you are inducing voltage potential from your body.

Just my observation today.

@ All:

I had another idea.  (I know this can be dangerous)  I was reading my latest All Electronics catalog and I found something interesting.

On page 59 there is a Gas tube Sign Power Supply advertised. Input is: 12 vdc and output is: 2,000 vac.  Now it says it needs 1 amp input to do this.  It also says that I can add another circuit they offer to get the output up to 25,000 volts.

So, I am thinking of getting this (it is only $6.50) and attempting to run it from my EER and a JT.  Now, I don't have the amp needed but, if I charge my supercap up and it is in paralell to the JT I believe I might be able to run this device.

If I can run it, my question is....if hooked up to a 48" tube, will the tube be like really bright at 2,000 volts?  And, if I add their other circuit, what would happen if I tried to light the tube with 25,000 volts?

To me, this is like when I used the modified Fuji circuit to do stuff.  this device might be another order of magnitude of output from my EER.

I am open for all opinions and comments on this.  (Jeanna, Xee2 and Jim, this means you.)

I have several JT toroid circuits that would give me the 12 volts I need.  I think I can get the 1 amp needed from my supercap.

Any thoughts?

Without the cap it don't work. I just have found that it works on both side of the resistor and the + side of the led but it's harder to do. The more easy to blink the led is still on the base transistor side of the resistor.

I just have make another video without shaking the joule thief to eliminate(i hope) some or most of the static electricity. The joule thief was on a sort of wood support, not on the soil, even i have no carpet on it. If i turn the wire like a coil it looks more easy to reproduce. I'm not sure but the frequency where i touch the resistor can play a role. Sometime i can make it blink a lot of time in a row but it's hard to do.

Maybe it has something to do with the electrical potential of my body but i have the feel that it pump a spike of electricity out of the cap. Or maybe it's like an antenna, i don't know.
